Treflan 5G, others
Common Name: trifluralin
Formulations: 5G, others
Uses: Selective preemergence control of annual grasses and broadleaf weeds in field- or container-grown nursery stock, landscape ornamentals, ground covers, and many annual and perennial flowers.
| Amount of active ingredient | Amount by formulation | |
| | 5G | |
Per Acre | 2 to 4 lb. | 40-80 lb. | |
Per 1,000 sq. ft. | | 1.8 lb. | |
Major Weeds Controlled: Annual grasses such as crabgrass, barnyardgrass, foxtail, and panicum. Annual broadleaves controlled include pigweed, lambsquarters, and chickweed.
Major Weeds Not Controlled: The following are generally not controlled: cocklebur, velvetleaf, jimsonweed, groundsel, Venice mallow, and nutsedge. Erratic or partial control of ragweed, purslane, and galinsoga has been observed.
For Best Results: Apply before germination of weed seeds or to clean, cultivated, weed-free areas. Must be incorporated within a few hours of application. Use lower rates if physically incorporated and higher rates if applied to the surface and watered in. May be combined with other herbicides for an expanded spectrum of weed control.
Cautions and Precautions: Do not apply granules to wet foliage. Not recommended for muck soils. Do not apply over 12 lb. AI/A within a 12 month period. This pesticide is extremely toxic to freshwater, marine, and estuarine fish and aquatic invertebrates. Do not apply to water or areas where surface water is present or to intertidal areas below mean high water. Do not apply or dispose of equipment in a way that will expose surface waters.
Residual Activity: Two to three months of residual control can be expected.
Volatility and Leaching Potential: Moderately volatile and subject to photodegradation. Insoluble; leaching is negligible.
Symptoms and Mode of Action: Inhibits root development by affecting cell division. Typical injury symptoms include swollen, stubby roots. These symptoms are most commonly seen on affected grasses. No significant absorption or translocation.
